Changes
Since the unique together functionality doesn't generate any indexes / constraints in MySQL / Oracle databases, the RunSQL commands that existed previously weren't relevant for those database engines. This PR ensures that this migration only applies to PostgresDBs.
How did you test this code?
This has been tested before (see
features.0036_remove_existing_constraints
migration here).
